◆ The PatternLatency budgets, error budgets, and avoiding alert fatigue
A Service Level Objective (SLO) defines what "good enough" means: "99.5% of predictions return within 200ms." The error budget is what's left — you can spend it on risky deployments. Too many alerts and people ignore them; too few and incidents go unnoticed.
Error Budget = 1 − SLO target
If your SLO is 99.5% availability, your error budget is 0.5% — roughly 3.6 hours of downtime per month.

Pattern bridge: Error budgets work like drawdown limits in trading — a predefined loss tolerance that triggers defensive action when consumed. The statistical foundation is the same confidence interval logic.
